Shingle-machine



UNITE STATES FURMAN HAND, JR., OF CHICAGO, ILLINOIS.

SHINGLE-MACHINE.

Specification of Letters Patent No. 9,115, dated July 13, 1852.

To all whom 'it may concern:

Be it known that I, FURMAN HAND, J r., of Chicago, in the county of Cook and State of Illinois, have invented cert-ain new and useful Improvements in Machines for Biving and Shaving Shingles; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part thereof, in which- Figure 1, represents a perspective view of the machine, and Fig. 2, represents a vertical longitudinal section through the lower part of the machine.

Similar letters in both the figures represent the same parts.

The nature of my invention consists, first, in so arranging and operating the riving and shaving knives in their ways or guides, as that after the shingle has been separated, or nearly so from the bolt, it will be carried forward by the bolt to the shaving knives, where it is nished, during which latter operation the riving knife remains stationary; also the double carriage, one resting upon or over the other', and so arranged that one shall feed up the bolt to the knife, while the other carries the riven shingle up to the shaving knives, the forward motion of the two carriages is simultaneous and uniform, but their motions when rearward are one upon the other.

To enable others skilled in the art to make and use my invention I will proceed to describe the same with reference to the drawings.

I construct a substantial frame of timber, consisting of the base A, front upright timbers B, and rear upright timbers C. Near the top of the front upright timbers B, I arrange side frames D, through all of which is passed, and supported in proper bearings the shaft E, having on one of its ends, a crank F to give motion to the several parts connected therewith. About the center of the shaft E, is arranged a crank formed of the two arms Gr, H, which are connected by a wrist pin I, to which is attached by an iron strap one end of the pitman J-the other end of said pit-man being similarly attached to a cross head K, moving in the guides L, L, on the inside of the front upright timbers B. To the lower or under side of the cross head is suspended by separate connecting rods M M, the shaving knives N, which are properly secured on stocks, and are set with an inclination to-ward each other the counterpart of the shape of the shingle t-o be formed. The knives N, with the stocks, move in ways O, which are properly tapered so as to allow them to cut the proper taper of the shingle, and said knives are formed something like a common chisel so that their whole fiat surfaces will rest against the shingie, and so that also their cutting edges shall be immediately opposite each other, which prevents the knives from eating into, the grain of the wood if the least crossgrained, or from drawing the shingle from one knife to the other, in either of which cases the shingle would be cut in two. Of the two arms G, I'I which form the crank for working the shaving knives-one of them (Gr) is longer than the other, which as the crank moves around with the shaft strikes a curved plane on the end of a hinged arm P, to which the pitman Qi, is attached and drives it down. To the pitman Q is attached a gate or knife frame D, Fig. 2, which moves perpendicularly in the guides S, S, in the front upright timbers B, to the lower end of which knife frame, is attached the riving knife T.

On the end of the arm Gr, is a pin U, which catches under a cam ledge on the top of the hinged arm P, by which said arm is raised up, after it has been forced down as above described. To the top of the frame is fastened a spring latch V, which extends down below the shaft E; and near the end of before mentioned hinged arm P is a pin A, which as the arm I) is raised up by the pin in the long arm G of the crank forces back said spring latch, until the catch therein comes opposite the pin a, when it is caught by said latch and upon which it rests, while the shingle is being operated upon by the shaving knives. The pin in the arm Gr, as soo-n as the arm P is caught and held by the latch, leaves the cam ledge, entirely separating itself from the arm P, by which means the riving knife is raised and held up out of the way, while the shingle is being finished by the shaving knives, and in proper position to be again driven down to rive off the neXt shingle.

On the outside of each of the top longitudinal pieces of the frame are arranged the arms IV, which are vibrated by the cams X, on the shaft E. To each of these arms are attached one of the ends of connecting rods b (one only being seen) the other ends being fastened to one of the arms of the bell cranksY, near the botto-m or base of the machine (one of which only can be seen). The bell cranks are fastened to the frame, by pins on which they may freely turn, and are placed with their arms in a reversed position toward each other, so that one shall run the carriage forward, and the other backward. In their lower arms which are suitably slotted for the purpose are arranged and supported the ends c, of a bar which is fastened to the underside of the lower car riage Z, and which said carriage is mo'ved forward and back, when the machine is in operation, to carry the bolt forward to feed up the shingle to the shaving knives, and back to place the bolt in proper position for the neXt operation. The carriage Z, moves in horizontal ways on the inside of the base timbers A, of the frame, and on top of said carriage is placed the upper carriage` d, to which the bolt of timber c, from which the shingles to be riven, is secured by dogs f, at top and bottom. The under carriage Z, has a longitudinal slot in it, through which projects a rack g, which is attached to the underside of the upper carriage d. Below the under carriage, and to which it is fastened or rather supported in bearings, in which it may turn, is arranged the shaft L, upon which is placed a spur wheel 2', so as to mesh into the rack g, aforesaid on the upper carriage. On one end of the shaft h, is placed the ratchet 7c, into which plays a pawl l. As the carriages are moved back and forth by the bell cranks, and as the shaft L, is attached to one of them, consequently it must move as well as the ratchet which it carries. F or admitting of this movement,

there must be a slot m, cut in the frame so as to allow. it to move with said carriages. As the carriages move back from the knives,

.ries the shingle forward after it is split from the bolt to the shaving knives, which K complete the shingle, and as they rise up, are forced apart by the inclined guides, and allows the shingle to drop out of the machine.

Having thus fully described my invention what I claim therein as new and desire to secure by Letters Patent isl. So combining and arranging the riving'knife, and the shaving knives, in their ways as that after the shingle has been separated or nearly so from the bolt, it will be carried forward by the carriage to the shaving knives where it is finished, and so that the riving knife shall remain stationary until the shaving knives have taken firm hold of the rived shingle, the whole being operated by the means substantially as herein described. y

2. l also claim in combination the double carriage-one moving on top, or over the other, and so arranged that one shall feed up the riven shingle to the knives and the other shall carry back the bolt at each operation of the machine sufficiently far to cut off one shingle therefrom, the whole being operated su stantially in the manner described.
